  • this "Fädelarbeit” is technically complicated assembly and expensive.
  • the sealing of the passage opening is particularly complex and therefore prone to premature failure of the desired sealing function. This increases the maintenance and repair work and the associated costs.
  • DE 37 01 597 A1 proposes first to thread a cable harness through a comparatively large steering through-hole, then to connect the cable harness in the radial direction into the comparatively small slot connected to the steering through-hole Insert cable penetration hole.
  • a steering through hole is present.
  • the prior art assembly only makes sense if the wiring harness is to be passed in the immediate vicinity of the steering column through the end wall. Otherwise, the cross section of the connecting wall passing through the end wall increases rapidly, so that the sealing of the connecting slot between the cable and steering passage hole with increased effort and the resulting disadvantages mentioned above is connected.

Since the line is used transversely to the line longitudinal direction in a first partial opening and subsequent partial openings additional partial walls subsequently to the first partial wall can be attached, the edges of the partial openings flank the circumference of the line particularly tight.
  • the passage opening of the wall is therefore kept particularly small in contrast to conventional constructions. Consequently, gaps between the conduit and passage opening can be sealed with little effort and simple sealing construction. This advantage in turn reduces manufacturing costs and improves the reliability of a seal used.
